Sticky: (Official) 370Z Clutch Pressure (CSC) Failures

ephan

within 10k miles I don't think that much moisture could be introduce into the system, could be as simple as the dealership didn't properly bleed the system. I am suppose to pick up my car this afternoon, with this situation dragging out over this long, my love for the z is becoming bipolar. thinking about just trading in the car rather than picking up the Z today.

Just found this thread. My synopsis is the clutch cylinder is probably ok. I would change it to a higher quality one though. The master might also need changing.

I just got mine done and not 2 weeks later the pedal started going again. First they were bitching because I had some bolt on stuff and they said they saw me AUTOX the car... I told them to fix the **** or go get the regional manager so we can take care of it... .along with some other choice words. There was air in the line this time due to me "boiling" the fluid. HORSESHIT! anyway. I would change the CSC (which I will do very soon) and might as well upgrade the clutch in the process. I have test pipes and catback so I can imagine it gets hot under there... no heat shield anymore. Maybe insulate the lines and change them out for steel lines. Upgrade the fluid for sure. I wish they would just recall this part and upgrade everyone but I guess everyone doesn't RACE their Z on the weekends... lmao. AUTOX is not racing... just like skateboarding is not a crime.... neither is autox. lol :-)

Could have been trapped air. After my second CSC replacement I noticed when driving home from the dealer that the engagement point was extremely low and did not feel right. I called the dealer immediately so that I could bring it in the following morning (I would have turned around right then and taken it back but needed to be somewhere and it was drivable). The next day the clutch felt back to normal and the symptom has not come back to this day (>1.5 years, 10k miles, and a track day). I chaulked it up to trapped air that worked itself out with a little modulation. Also keep in mind that if improperly adjusted by the dealer the CSC or CMC could be over extending causing a failure or sucking in air.

Hang in there and don't give up yet...I was pretty frusterated when I went through 2 CSC's in 6 months and the car was <1year old but (knock on wood) since then all has been good.
